To provide a sensible heat recovering method of combustion exhaust gas by which high-temperature purified gas is obtained efficiently from the high-temperature combustion exhaust gas containing a metal corrosion component.

The combustion exhaust gas containing the metal corrosion component is supplied to thermal storage chambers 2A, 2B filled with thermal storage medium S made of ball-shaped ceramics, and the thermal storage medium made of ball-shaped ceramics in such thermal storage chambers is heated there. Thereafter, first gas is supplied to these thermal storage chambers and such gas is heated there. This heated first gas and second gas are heat- exchanged in a tubular indirect heat exchanger 6. Thus, the sensible heat of the combustion exhaust gas is recovered.
